Abstract

Des systèmes et méthodes de détection dune charge de frigorigène dans un système de refroidissement sont décrits. Les systèmes et méthodes comprennent la réalisation dau moins une pompe partielle du frigorigène en surveillant un ou plusieurs paramètres. Les paramètres mesurés peuvent être comparés à une norme afin de déterminer si une fuite de frigorigène sest produite ou pour déterminer dautres renseignements sur le frigorigène. Dautres systèmes et méthodes sont décrits.
